We divide 825561 by 70
The aim is to understand the frequency of 70 in 825561.

Advancing to step 1:
If we divide 8 by 70, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 70

Step 2:
If we divide 82 by 70, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 70 from 82, we get 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 70

Let's proceed to step 3:
125 divided by 70 is 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 70 from 125 leaves us with 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 70

Step 4:
70 can be fit into 555 7 times, resulting in a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtract 490 from 555 to get 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 70

Advancing to step 5:
If we divide 656 by 70, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 1179.0
If we subtract 630 from 656, we get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 70

On to step 6:
The number 70 fits into 261 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 11793.0
Subtract 210 from 261 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
If we divide 510 by 70, we get 7 and a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 11793.7
Deduct 490 from 510 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
70 can be fit into 200 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11793.72
Subtract 140 from 200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 70 fits into 600 8 times, leaving a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 11793.728
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
When dividing 400 by 70, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11793.7285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
If we divide 500 by 70, we get 7 and a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 11793.72857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
100 divided by 70 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11793.728571
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 11793.7285714
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 11793.72857142
Deduct 140 from 200 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 11793.72857142 with a remainder of 6e-08.
